ipv6calc sneak preview pre 0.94
by Peter Bieringer 10 Apr '13

10 Apr '13

Hi, ipv6calc sneak preview pre 0.94 is ready for testing, final release is planned for next weekend. It took while after 0.93 to implement new features. Major new features: - IID privacy detection - implement filter mode (-A filter) - reliable IPv6 address anonymization (means all IPv6 address type information is kept while anonymize the rest [SLA, unique values in IID] - ipv6calcweb.cgi form mode, see here: http://ip.bieringer.de/cgi-bin/ipv6calcweb.cgi See changelog for more: http://cvs.deepspace6.net/cgi-bin/cvsweb.cgi/ipv6calc/ChangeLog?rev=1.285;c… Hope this helps, Peter

Hmm, in principle, this can be implemented, but this must be proper implemented e.g. by giving a prefix. Will take a look how difficult this would be, perhaps in upcoming 0.94.0 release (work in progress since longer time) this will be implemented. Regards, Peter

sneak-preview: IID privacy detection & filter capabilties implemented
by Peter Bieringer 01 Apr '12

01 Apr '12

Hi, I've extended ipv6calc with filter capabilities for the pipe mode, e.g. you can filter from a big list of IP(v4|v6) addresses the one you want depending on type, e.g. ./ipv6calc -q -m -i 2001:db8:0:1:2c73:ffff:1234:5678 | grep TYPE IPV6_TYPE=unicast,global-unicast,productive,iid-privacy,iid,iid-local $ echo "2001:db8:0:1:2c73:ffff:1234:5678" | ./ipv6calc -A filter -E iid-local 2001:db8:0:1:2c73:ffff:1234:5678 and as you see, this address was also detected as being a generated privacy one (which is in this case a not so good example...one of the minor false-positives). Filter also supports negation by leading "^" and also more of one filter is configurable like: cat <file> | ./ipv6calc -F -A filter -E ^iid-privacy,^iid-eui48 Online help and documentation lacks still a little behind :-( The iid-privacy detector catches over 99.9% of 1 million generated ones. So one can now test whether his system uses a generated IID based on privacy extension by browsing to: http://mirrors.bieringer.de/cgi-bin/ipv6calcweb.cgi if IPV6_TYPE contains iid-privacy, the detector means the IID is such a one. Happy testing. BTW: If you will contribute on improvement of the IID privacy extension detection, see undocumented script: test_privacyiid_detection.sh This can create a bunch of privacy extension based addresses and detection code in lib/libipv6addr.c (ipv6addr_privacyextensiondetection) Currently I've implemented some simple statistical analysis only... I plan to release 0.94.0 in the next weeks. Regards, Peter

ipv6calcweb.cgi new feature: form mode
by Peter Bieringer 01 Jan '12

01 Jan '12

Hi, I've implemented a form mode into ipv6calcweb.cgi to be able to retrieve information depending on user input. Example: http://mirrors.bieringer.de/cgi-bin/ipv6calcweb.cgi Also I've added support for configuration of ipv6calcweb.cgi via SetEnv, so there should be no need anymore to touch the script itself for config changes. ## program controls by httpd's setenv # HTTP_IPV6CALCWEB_MODE : info (default), form (display a form for user input), mixed (both) # HTTP_IPV6CALCWEB_INFO_SERVER : 0 (default), 1 (show information about server) # HTTP_IPV6CALCWEB_DEBUG : 0 (default) # HTTP_IPV6CALCWEB_DB_IP2LOCATION_IPV4 : IP2Location IPv4 database file (optional) # HTTP_IPV6CALCWEB_DB_IP2LOCATION_IPV6 : IP2Location IPv6 database file (optional) # HTTP_IPV6CALCWEB_DB_GEOPIP_IPV4 : GeoIPv4 database file (optional) # HTTP_IPV6CALCWEB_DB_GEOPIP_IPV6 : GeoIPv6 database file (optional) # HTTP_IPV6CALCWEB_BIN_IPV6CALC : path to ipv6calc binary (optional) Please use latest code from CVS to play around. Regards, Peter

support of IPv6 literal addresses implemented
by Peter Bieringer 26 Nov '11

26 Nov '11

Hi, I've implemented now the support of IPv6 literal addresses, used e.g. in Microsoft OS. http://technet.microsoft.com/en-us/library/bb726965.aspx $ ./ipv6calc --out ipv6literal --examples ... Print a given IPv6 address in literal format depending on format options: Uncompressed, e.g. 2001:db8::1 -> 2001-db8-0-0-0-0-0-1.ipv6-literal.net Full uncompressed, e.g. 2001:db8::1 -> 2001-0db8-0000-0000-0000-0000-0000-0001.ipv6-literal.net Compressed (default), e.g. 2001:db8::1 -> 2001-db8--1.ipv6-literal.net also this format is supported on input, e.g. $ ./ipv6calc 2001-db8--1.ipv6-literal.net No input type specified, try autodetection...found type: ipv6literal 2001:db8::1 In addition, 2 additional formats for MAC addresses are supported now: xxxxxxxxxxxx (seen on some network devices) xxxxxx-xxxxxx (seen on HP switches) Features are added to current CVS version at the moment.

6rd address anonymization?
by Peter Bieringer 16 Sep '11

16 Sep '11

Hi, according to the RFC the IPv4 address is somewhere stored in the prefix. Is there any common practice, where it is usually stored to get a chance to anonymize? Regards, Peter
